I have an 09 EX-V6 with a little over 20k miles. Tonight while driving to the store, I heard a noise that sounded like something was grinding...almost metal to metal. I was driving about 60mph and wasn't pressing on the gas so I didn't think it was me and figured it was the car next to me. When I touched the brakes the noise changed. I just a few hard steps and the sound went away, that's when I realized it was me. On the way home, same thing, but I stomped on the brakes a few times and the sound kept coming back. The rear brakes have only just start to squeal when they are cold and right before December I checked my pads and they were fine, about 60% left in all pads. Any idea what the grinding noise could be? Sounded like it was coming from the driver side front but I'm not 100% sure. Could it be the pad is grinding against the rotors meaning the spring broke? when the sound starts and I step on the brakes a few times, it does go away and doesn't come back. Any ideas would be great. Thanks! Might just have to take it to the dealership if they are willing to do a free inspection.
